TYPE-B AR.

To all where it may concern:

Be it known that I, EDWARD E. TALIA- FElino, a citizen of the United States, and a resident of Colorado Springs, in the county of El Paso and State of Colorado, have invented a new and Improved Type-Bar, of which the following is a full, clear, and exact description.

This invention relates to type bars and "more particularly to type bars used in connection with writing machines and the like.

An object of the invention is to provide a type bar for producing a plurality 0t original, duplicate impressions by, a single movement of the bar.

A further object of the invention is to provide a type bar for use in combination with a plurality of platens and designed to produce duplicate impressions simultaneously at the platens.

A still further object of the invention is to provide a type bar designed to produce a plurality of duplicate, original impressions by 'a single movement of the bar, and so arranged that all the impressions are made with equal force and distinctness.

The invention consists in the construction and combination of parts, to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawin s forming a part of this s )cciiication, in whic similar characters of re 'erence indi eate corresponding parts in all the views, and in which Figure l is a side elevation showing my type bar together with a pair of platens; Fig. 2 is a front elevation of the type bar; Fig. 3 is a rear elevation of the type bar; and Fig. 4 is a transverse section on the line 4 of. Fig. 1.

Before proceeding to a more detailed explanation of my invention, it should be stated that it is l'ieccssary to execute fully 95 per cent. of all writing produced by writing inachines, in duplicate. By means of my type bar used in conmrction with suitably constructed writing machines, it is possible to Write simultancously two copies of equal clearness and positive exactness, thus saving much time. and entirely doing away with many inconveniences and possibilities of error .whcre carbon paper or co )y book devices are used. To accomplisht iis l employ a single type bar having a movable section Specification of Letters Patent.

Application filed October 3, 1907. Serial No. 395,693.

Patented June 22, 1909.

paper carried by the platens are of equal clearncss, as the characters carried by the typcbar are impressed with equal force against the platens. It will be understood that by the word duplicate as applied to characters is meant similar characters; for. instance, a capital A and a second or duplicate capital A; a small a and a second or duplicate a. My type bar can also be. provided with duplicate sets of letters, and is -then:ulaptml for use in connection with typewriting machines and the likoin which the type bar is shifted lor the \vritingol certain di'll'crcnt charm-tors. By a "duplicate set of characters is meant, for example, a capital r\" and a small "at", and a second or dupli-.'

small "a". ll' so desired, carbon copies can also be executed at car-h platen, thereby in- .crcasing the number of copies produced.

A ribbon or other inking medium of common orprcl'rrrcd type, is to be used with my improved type bar where the same is employed in a machine ol' the usual construction. it necessary, a ribbon may be cmploycd [or each charact or or set 01' characters.

The construction ol' the type bar, aside ll'Olll my improvements, may be olany commen or prcl'errtal form or ol' any kind used in writing machines. The operating mechanism, the means for mounting the type bar, and other details have no ronncctionwitll my present invention.

ltol'crringmore mrtirularly to the drawing's, I, provide a main type bar 1,'which may brl'ashioncd l'rom any suitable material and may be ol' any lorm usually or most convenr icntly employed. The main bar 1, at the end l'tllltllt hour the keys, is laterally disposed and (arrics an ollsct, elongated head 2 prcl'crably parallel to the adjacent body of the main bar. hour the center, the head 2 has a laterally extending our 3, provided with an opening therethrough, in which is with suita le openings for the urpose. The

section 5 is slotted and has t e sides 7 ar' ranged adjacent to the sides of the head 2. Near the ends the section 5 has parallel working faces 8, upon which are provided types or characters 9. The arran ement is such that the faces of the types or c aracters are alined with each other and with the pivot pin 4.

The platens 10, which may be of an common or preferred form, are arranged a jacent to the respective working faces of the type bar section 5; the latter, near each end, behind the working faces 8, has an integral yoke 11, which is arra'n ed to engage the head 2 of the type bar and limit the working movement of the movable section. The Working faces are formed 011 blocks 12, which are secured in position between the sides of the movable sections by means of pins 13. The head 2 and the blocks 12 are suitably beveled to ermit the swinging movement of the movab e member of the type bar.

As the character-carrying section of the type bar is movable pivotally with respect to the main type bar, the characters are projected with equal force against the res ective platens that is, the force applied to t e type ar is equally distributed between the Working faces of the movable type bar section, owing to. the automatic adjustment of the latter inr'striking against the platens. As the characters are alined with the pivotal point of the movable section, the characters will swing squarely against theplatens at each imIpression, thereby obviating blurring of the etters-in writing, while permitting several degrees of play to allow for the automatic adjustment of the working faces.

Having thus described my invention I claim as new, and desire to secure by Letters Patent:.

1. A type bar having a member pivoted thereonintermediate its ends, said member at each side of its pivotal point having a printing face, and back of each printing face a stop adapted to engage the type bar to limit the swing of said member.

2. A type bar having a member pivoted thereon and free to swing to adjust itself in contacting with a plurality of platens, said member having rinting characters at each side of its pivota point, and means for limiting the swing of said member, the pivotal point of said member lying substantially in the plane of said characters.

3. A type bar com rising a main bar having a section movablb with res ect thereto and provided with duplicate c aracters at each side of its connection with said main bar whereby said section can adjust itself automatically in making duplicate impresceases oint of said section, said section having a united freedom of movement to adjust itself automatically when contacting with a plurality of platens, the distance between said section and its connection with said main. bar being less than the distance separating said duplicate printing characters.

5. A type bar,,comprising a main bar having a head, a section pivoted upon said head intermediate the ends thereof, and at the opposite extremities having working faces provided with printing characters, means carried by said section and adapted to engage said head to limit the movement of said section, said head and said working faces at the adjacent sides being inclined and having the inclined surfaces lying in planes passing through the ivotal center of said section. I

6. A ty e ar, comprising a main bar have ing an e ongated head, a section having spaced sides and pivoted upon said head, whereby said sides are arranged at the sides of said head, said section near the ends having working faces provided with printing characters, said section further, at each end opposite the respective printing face, having a yo (e ada ted to be positioned at the back of said head whereby the movement of said section is limited, said head and said printing faces at the adjacent sides being radially inclined. a

7. The combination, with a plurality of platens, of a type bar having a member pivoted thereon and free to swing to'adjust itself in contacting with said platens, said member having printing characters at each side of its pivotal point, and means swing of said member.

8. The combination, with a plurality of platens, of a type bar com rising a main bar iaving a section mova 1e with respect thereto and provided with duplicate charac ters at each side of its connection with said main bar whereby said section can adjust itself automatically in making duplicate im pressionsat said p atens, and means for limfor limiting the itin the "swin of said member. b

9. A tlype bar comprising a main bar havlng an e ends with a laterally extending ear, and a movable member rovided with ears pivotally connected with said. ear of themain bar, the said member being provided near its ends with printing characters located in alinement with the pivotal point of said member.

10. A type bar comprising a main bar havongated head provided between its 1 ing an ofi'set elon ated head extending par allel to the'body 0 the bar, the said head being rovided at its centerwith a laterally exten ing ear, a movable slotted section having its sides arranged adjacent to the sides of the head, the said section bein provided with ears pivotally connected wit 1 the ear of said main bar, the said section having near its ends parallel working faces provided with printing characters, the faces of the )rinting characters being alined with each ot er and with the pivot of said section.
